Opacity
Opacity refers to the transparency or opaqueness of paper. Papers with lower opac-
ity tend to let text and images show through more than papers with higher opacity.
Opacity is expressed as a percentage in paper. For example, paper with 98 % opacity
means that 98 % of light is not allowed to pass through the paper.
Select the
Opacity
function from the mea-
surement functions menu.
Place the sheet of paper to be a measured on
a black backing.
In the next step take a measurement of the
same sheet of paper after you have placed
it on a stack of white paper (minimum 50
sheets).
Now the measurement device displays the
result of the opacity measurement.
For further measurements just press the enter
button and repeat the whole procedure.
